How to Program Processor for DMA

[joe306]

Hello, I need to learn how to program an ARM processor on  ZCU-106 board to do a DMA from/to the PL side. I'm trying to interface with an Aurora 64B/66B IP over AXI DMA. I found some examples at:

https://github.com/Xilinx/embeddedsw/tree/master/XilinxProcessorIPLib/drivers/axidma/examples

I looked over the example but I'm not seeing where the data is being transferred from the PS to the PL and from the PL to the PS.

Are there any other examples that can help?

Thank you,

Joe

Hi @joe306 ,

We have an example that is designed for transfer data from the counter in PL to PS DDR and PS DDR to AXI stream FIFO in PL for verifying. Please refer to the below answer record.
